php使用while循环和mysql_fetch_array()函数获取(解析)mysql数据

源码如下：

 <?php
 /* by http://www.manongjc.com */
 $conn = @mysql_connect( "localhost", "userName", "password" ) or die( "Err:Conn" );

 $rs = @mysql_select_db( "my_database", $conn )  or die( "Err:Db" );

 $sql = "select id,first_name from my_table order by first_name";

 $rs = mysql_query( $sql, $conn );

 while( $row = mysql_fetch_array( $rs ) )
 {
   echo( "ID: " . $row["id"] );
   echo( " - FIRST NAME: " . $row["first_name"] . "<br>" );
 }

 ?>
